CleanAIR Systems, Inc. announced that its diesel catalytic converter has recently received certification by the Swedish Government for both on- and off-road use under the Swedish Environmental Zones program. The converter can be used on diesel-powered trucks and buses, as well as heavy construction equipment.
The certification testing was performed by AB Svensk Bilprovning Motortest Center on a chassis dynamometer using a MB609D bus with a Mercedes OM364 diesel engine. To simulate the worst-case scenario of stop-and-go driving and low exhaust temperatures, the test cycle used was the "Braunschweig City Driving Cycle," representing a typical driving pattern for a bus or delivery truck traveling a city route.
The Swedish Environmental Zones program requires an 80 percent hydrocarbon reduction for both on- and off-road vehicles and a 20 percent reduction in diesel particulates for on-road vehicles. The CleanAIR Systems converter reduced hydrocarbons by 86 percent, diesel particulate matter by 43 percent, carbon monoxide by 91 percent and nitrogen oxides by 13 percent.
CleanAIR announced earlier that another of its products, a diesel filter system, received the Swedish certification.
